Doom64 EX

Doom64 EX is a reimplementation of Doom 64 for Linux, macOS, Windows, and Nintendo DS by Samuel "Kaiser" Villarreal. It is based on Doom3D, though rewritten for rather than, and includes many bug fixes from Boom and MBF. It aims to recreate the look and feel of Doom 64 as closely as possible, based on specifications obtained through, similar to how Kaiser also created SvStrife and Chocolate Strife.

Details
Doom64 EX is currently the only source port with support for the Doom 64 campaign through use of the game's native data, along with a nearly 100% accurate recreation of the game's unique modifications to physics, balance, and rendering. Due to the drastic modifications made to the Doom engine for the original game and its PlayStation predecessor, it is difficult to support in any way other than through a port dedicated to the purpose.

Compared to the Doom 64: Absolution TC, the principal difference is that Doom64 EX uses the original data. A tool provided with the port can create a DOOM64.WAD IWAD from a Nintendo 64 ROM dump. Neither the ROM nor any instructions on how to obtain it are provided with the port, for copyright reasons.

Newer versions of the port add features which go beyond those supported by the original game, including precalculated light maps and a generic "nightmare" property that can be applied to any monster.

Version history
The first public version of Doom64 EX was released on July 10, 2008. The latest version is, released on.

As of August 2018, the port was still in active, albeit slow, development. Changes since the 2.5 version include moving the development home from SourceForge to GitHub, compilation fixes for newer operating systems, and integration of the WAD conversion feature directly into Doom64 EX.

Following the announcement of the official remaster, no further updates other than a list of differences between its latest version and the 2020 remaster have been published.

Custom content usage
Doom64 EX, as with most other Classic Doom source ports, supports custom WAD files, including but not limited to mapsets and graphic replacement WADs. To date, it is still actively used for custom mapsets due to significant technical differences with the 2020 remaster.
